[texts]KNBD: A Remote Kernel Block Server for Linux - Becker, Jef
I am developing a prototype of a Linux remote disk block server whose purpose is to serve as a lower level component of a parallel file system. Parallel file systems are an important component of high performance supercomputers and clusters. Although supercomputer vendors such as SGI and IBM have their own custom solutions, there has been a void and hence a demand for such a system on Beowulf-type PC Clusters...

[texts]Dominant Presence of Oxygenated Organic Species in the Remote Southern Pacific Troposphere - Singh, H.
Oxygenated organic species are intimately involved with the fate of nitrogen oxides (NOx) and hydrogen oxides (HOx), which are necessary for tropospheric ozone formation. A recent airborne experiment (March-April, 1999) focused over the Southern Hemisphere (SH) Pacific Ocean (Pacific Exploratory Mission-Tropics B (PEM-Tropics B)) provided a first opportunity for a detailed characterization of the oxygenated organic composition of the remote Southern Hemisphere troposphere...

[texts]The Standard-Accretion Disk Dynamo - Rudiger, G.
We consider the classic MHD turbulent dynamo operating in a thin, Keplerian accretion disk powered by turbulent viscous stress. The character of the turbulence is encapsulated into two constant parameters: the Shakura-Sunyaev dimensionless viscosity, alpha(sub ss), and the Coriolis number, omega = 2tau(sub corr)omega. The dependence of the total electromotive force on alpha(sub ss) and omega is derived and the dynamo-generated magnetic field is calculated in both kinematic and nonlinear regimes ...

[texts]An IDEA of What's in the Air - NON
The Automatic Particle Fallout Monitor (APFM) is an automated instrument that assesses real-time particle contamination levels in a facility by directly imaging, sizing, and counting contamination particles. It allows personnel to respond to particle contamination before it becomes a major problem. For NASA, the APFM improves the ability to mitigate, avoid, and explain mission-compromising incidents of contamination occurring during payload processing, launch vehicle ground processing, and poten...

[texts]Motion of Major Ice Shelf Fronts in Antarctica from Slant Range Analysis of Radar Altimeter Data, 1978 - 1998 - Zwally, H. J.
Slant range analysis of radar altimeter data from the Seasat, Geosat, ERS-1 and ERS-2 databases are used to determine barrier location at particular times, and estimate barrier motion (km/yr) for major Antarctic ice shelves. The barrier locations, which are the seaward edges or fronts of floating ice shelves, advance with time as the ice flows from the grounded ice sheets and retreat whenever icebergs calve from the fronts...

[texts]Atomic Physics with the Goddard High Resolution Spectrograph on the Hubble Space Telescope - Zsargo, J.
High quality spectra of interstellar absorption from C I toward beta(sup 1) S(sub co), rho O(sub ph) A, and chi O(sub ph) were obtained with the Goddard High Resolution Spectrograph on HST. Many weak lines were detected within the observed wavelength intervals: 1150-1200 A for beta(sup 1) S(sub co) and 1250-1290 A for rho O(sub ph) A and chi O(sub ph). Curve-of-growth analyses were performed in order to extract accurate column densities and Doppler parameters from lines with precise laboratory-b...

[texts]Flight Demonstration of a Shock Location Sensor Using Constant Voltage Hot-Film Anemometry - Moes, Timothy R.
Flight tests have demonstrated the effectiveness of an array of hot-film sensors using constant voltage anemometry to determine shock position on a wing or aircraft surface at transonic speeds. Flights were conducted at the NASA Dryden Flight Research Center using the F-15B aircraft and Flight Test Fixture (FTF). A modified NACA 0021 airfoil was attached to the side of the FTF, and its upper surface was instrumented to correlate shock position with pressure and hot-film sensors...

[texts]Hydrogen Molecules in SN 1987A - Culhane, Michael
The observations of CO and SiO in the infrared spectrum of SN 1987A clearly indicate that molecules can form in the debris of a supernova explosion. Since H2 is not easily observable we compute its abundance theoretically. For conditions typical of the inner (v less than 2500 km/s) envelope of SN 1987A, the fraction of H that is in molecular form rises to approx. 1% by t approx. 800 days. For t less than 500 days the formation is dominated by the gas-phase reactions H H() yields H2() hv; H2() H ...

[texts]Research in millimeter wave techniques - Mcmillan, R. W
The areas of millimeter wave (MMW) research include atmospheric propagation and radiometry, advanced MMW component design with emphasis on quasi-optical techniques, and the development of MMW receivers, especially those using subharmonic mixers. Calculations of atmospheric attenuation and radiometric antenna temperature were made in the range 100 to 700 GHz, together with measurements of atmospheric antenna temperature near 95 and 183 GHz...
